Ok, lets go about this in a logical way. Lets rule out things if we can
1) Could it be a flux capacitor?
Since theres no way hooking up a OBDII will be able to detect it. We have to do real life field testing.
On page 1398, section 3a of your owners manual it outlines what you have to do. But since Im such a nice guy Ill just tell you what is says.
"Find a 1/4 mile stretch of straight road in an urban setting. From a standing start, accelerate to 99 mph. If your car is equipped with the "Sync Flux Capacitor" option, you should see a bright flash and find yourself in another location.
If your car is NOT equipped with the Sync Flux Capacitor option, instead of seeing a bright flash, youll be seeing stars, but still find yourself in another location. It will have a big sign above it that reads: EMERGENCY ROOM".
2) NSA Tracking device:
Give em a call and ask them if its a tracking device. I understand they're open 24 hours a day ;-)
